Simple, practical and cheap
The projects must be simple to build by non-specialists and use cheap materials widely available.

With an educational value
The projects are mainly intended for teachers looking for ideas allowing pupils to :

• Understand better scientific matters
• Understand better the world
• Be more aware of the environmental issues

Neutral and harmless
The DIY Sciences Projects must be neutral, non-political, not commercial with only an educational purpose. The projects must be harmless to build and use.
